Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 103,623,685, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 103,623,685 | |
| -1 | -103,623,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,623,685.
Example:
1 x 103,623,685 = 103,623,685
and
-1 x -103,623,685 = 103,623,685
Notice both answers equal 103,623,685
With that explanation out of the way, let's continue. Next, we take the number 103,623,685 and divide it by 2:
103,623,685 ÷ 2 = 51,811,842.5
If the quotient is a whole number, then 2 and 51,811,842.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 103,623,685 | |
| -1 | -103,623,685 |
Now, we try dividing 103,623,685 by 3:
103,623,685 ÷ 3 = 34,541,228.3333
If the quotient is a whole number, then 3 and 34,541,228.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 103,623,685 | |
| -1 | -103,623,685 |
Let's try dividing by 4:
103,623,685 ÷ 4 = 25,905,921.25
If the quotient is a whole number, then 4 and 25,905,921.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 103,623,685 | |
| -1 | 103,623,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 257 | 1,285 | 2,827 | 7,331 | 14,135 | 36,655 | 80,641 | 403,205 | 1,884,067 | 9,420,335 | 20,724,737 | 103,623,685 |
| -1 | -5 | -11 | -55 | -257 | -1,285 | -2,827 | -7,331 | -14,135 | -36,655 | -80,641 | -403,205 | -1,884,067 | -9,420,335 | -20,724,737 | -103,623,685 |
